This invention relates to improvements in metal yarn spools particularly of the type adaptable for use on Axminster looms and.

it is the general object of the invention to provide a simplified construction wherein the spool heads will be held to the tubular barrel by means of integral extensions on the latter.

Axminster spools have wound thereon the variously colored yarns which enter into and determine the pattern of Axminster fabrics and these yarns are located between the heads on the ends of the yarn supporting barrel. The end yarns in contact with the 16 spools should be supported laterally as though they were in contact with-a plane surface so that the succeeding wraps will be properly supported and of the same diameter as the corresponding wraps of other yarns spaced from the spool head. It is an important object of my present invention to provide a steel spool head which is held in position by integral readily extending arms or the like projecting from the tubular barrel '25 and received by recesses or depressions in the interior surfaces of the heads in such away a to ive the end yarns proper support. It is a urther object of my invention to form the spool head with a slight central uiding web or ofi'set to center the head on the arrel and to extend integral cars from the barrel to enter recesses in the head, the web reinforcing the ears-and assisting them in preventing lateral displacement of the head. A further object is to sink a non-circular recess in the interior surface of the spool head and substantially fill it with a radial flange or ears integral with the barrel, theoutline of the recess being preferably possessed of practically no portion which is concentric with the barrel axis.

With these and other objects in view which will appear as the description proceeds, my

end of a spool made according to the preferred form of my present invention,

F F1g1. 2 is a vertical section on line 2-201 Fig. 3 is an end elevation of the spool head,

Flg. 4 i a perspective view of the end of the spool of a form shown in Fig. 1,

' Fig. 5 is a View similar to Fig. 2 but showin t e first modification, 1

Fig. 6 is a view similar to Fig. 4 showing the spool embodying the first modification,

Fig. 7 is a view taken along line 77 of Fig. 5, and

Fi 8 is a view similar to Fig. 6 but showing t e groove for a yarn retaining rod and constituting the second modification.

Referring to the preferred form seen in Figs. 1 to 4, I have shown a hollow tubular metallic barrel 10 from the end of which extends as shown herein four radially projecting integral arms 11 all of which are preferably located ina single plane perpendicular to the axis of the barrel. The spool head 12 has a flange 13 which, however, is not essential, and has a yarn engaging wall 14' into which is struck a recess 15 preferably of the form shown in Fig. 3. The recess has radially extending pockets 16 with an intermediate portion 17 of less radius. The recess is such as to receive the flanged extension or arms of the barrel, the arms 11 being located in the pockets l6 and the connecting flange 18 of less radius being located in the smaller portions 17.

The head may have an inwardly pressed centering web or offset 19 of such size as to fit into the tubular barrel for the purpose of locating the head concentrically with respect to the barrel and thus position the gudgeon 20 in axial alignment with the barrel. The arms 11 may then be secured to the head. asby welding. In the preferred form and as particularly shown in Fig. lthebottom of the recesses is offset to the left with respect to the wall 14, while the web 19 extends to the right of the wall. A reference to Fig. 1 will show that the centering web 19 which projects within the tube engages the interior of the latter and assists in preventing latill and located eral displacement of the head with respect to the aris oi the spool.

lln the first modification shown in Figs. 5, 6 and l the web 19 is omitted and the head is provided with a depression 30 which as shown in Fig. 5 communicates with a plurality of radially extending" pockets or reccsses 31 the bottom of each of which may be substantially parallel to the arm engaging surface 32 as in the preferred form. The barrel in this form of the invention is provided with ears or extensions 33 which project outwardly from the tubular barrel and are unconnected by any flange corres 0nding to that designated at 18 in the preierred form. The end of the tube preferably aligns with the outer surface of the cars 33 as suggested in Fig. 7, and the result of this construction is that those portions of the barrel which lie between the ears extend through the vertical wall of the spool head. he in the preferred form the depth of the recesses 31 is equal to or slightly in excess of the thick" ness of the cars 33 and the latter substan tially fill the recesses and are secured there= in, as by welding.

In the third form of the invention 1 set forth a spool adapted more particularly for that practice wherein a clamp bar holds the ends of the yarn in position until the spool is wound, after which the bar may be with-- drawn. In order to receive the bar not shown l provide the tubular barrel with longitudinal roove 4:0 of appropriate depth etween adjacent radially en tending integral cars 41. The head is pro= vided with a hole t2 formed in the depres sion and so related with respect to the recesses is: as to be always in correct aligm Inert with the groove 40. in this way the previously mentioned rod may be extended through the head or withdrawn through the hole 42 after the winding operation has been completed.

From the "foregoing it will be seen that l have provided a simple form of all metal .hxnainster pool having the end thereof upset so as to form an integral flange ertension in a plane substantially perpendicular to the barrel axis. 'lhese extensions substan tially fill recesses in the steel head which are of such depth that the yarn engaging portions of the head and barrel extensions are located practically in the same plane. In this way the end yarn neat to the spool head is permitted to lie properly and wind up in the same manner as do the yarns which are not in contact with the spool head. lln the preferred form it will be noted that the inwardly extending centerin ofi'set or web 19 serves also to reinforce t e radial extensions of the barrel and efiectively assist the latter in resisting lateral displacement of the head relatively to the barrel axis. in each of the modifications, on the other hand, the

ascents centering or the head is accomplished by allowing the barrel and to project into the depression in the head from which extend the radiating recesses, Also, in the last form described, the longitudinal groove is aligned with the hole in the head by the ears or the barrel extending into the recesses of the head.

Having thus described my invention it will be seen that changes and. modifications may be made therein by those skilled in the art Without departing from the spirit and scope of the invention and I do not wish to be limited to the details herein disclosed, but what I claim is:

1. In a yarn carrying spool, a hollow metallic barrel, on inmgral radial extension projecting outwardly from the barrel, a spool head formed of sheet metal and having an inner yarn engaging surface having a. recess therein which is non-circular in outline and v of a depth equal substantially to the tbiclo ness of the extension, the latter substantially filligg the recess and secured therein to the hen 2. in a yarn carrying spool, a metallic tubular barrel having radially spaced eatensions integral therewith and projecting from an end thereof, the outer surfaces of the extensions being in substantially the same plane as the end portions of the tube between said extensions, a spool head having recesses struck therein and having a depression in the central portion thereof, the recesses communicating with the depression and bein of a depth substantially equal to the thickness of the extensions, the latter lying in and substantially filling and being secured in the recesses, that portion of the head between the extensions engaging and being reinforced by that part of the barrel located between the extensions.

3. In a yarn carrying spool, a metallic tubular barrel having radially spaced extensions integral. therewith and projecting from an end thereof, the outer surfaces of the extensions being in substantially the same plane as the end portions of the tube between smTd extensions, a spool head having recesses struck therein and having a depression in the central portion thereof, the recesses communicatin r with the depression and being of a depth substantially equal to the thickness of the extensions, the latter lying and substantially filling and being secured in the recesses, the barrel having a groove extending longitudinally thereof and located be tween two adjacent extensions and the head having a notch located between the recesses corres onding to said two extensions, the notch eing held in alignment with the groove of the barrel by the extensions and recesses.

t. in a yarn carrying spool, a metallic tubular barrel, radial integral extensions projecting from the end of the barrel, a head having a central depression aligning with lltl llti

the barrel, the head having therein radiating from the depression, said extensions located in the w: and secured to the head and the surfaces of the extension olpposite the relying insubstantially t e same plane as the face of the head havin the recesses, and those portions of the barre between the extensions extending into the depression beyond said plane to support the inner'coil of the end yarn in contact with the said surfaces.

In testimony whereof I have hereunto afiixed my. signature.
